Indeed, that does not look like a bone of your regular four-legged animal, since they usually have elongated radius and ulna, and shortened humerus (and the same applies for the hind legs as well). Unfortunately the palm is missing and without that my expertise is not enough to tell what mammal would possess this kind of limb.

I'm afraid that even if police considered it as human bones, they would perform only microsatellite test, not whole genome sequencing, which would you need to identify the species (or at least partial sequencing).

Actually now as you said that, it does look bit like a leg, since in the arm the radius and ulna are much more closer in size than what are the tibia and fibula in the shin, and there is quite apparent neck and head visible on the upper part of the bone, which I think is missing in the arm.

However, I think the neck and head of the femur (if that even is a femur) are heavier or more prominent at least in adult humans - is there any indication of the size of that bone?

So, it still looks a bit odd for a human bone... but at least it is not a deer bone unless I'm completely mistaken!
